The Premise
The complete 3rd season of the hit TV series Justified on DVD. Justified is an American television drama series developed by Graham Yost. It is based on Elmore Leonard's novels Pronto (1993) and Riding the Rap (1995), and Leonard's short story “Fire in the Hole”. In the nonstop, gunslinging third season of the highly acclaimed hit series, Deputy US Marshal Raylan Givens (Timothy Olyphant) must wield his brand of renegade justice against modern crime like never before. Surrounded by dirty politicians, drug cartels, murder frames, hidden fortunes and multiple criminal forces warring for control – including archenemies Boyd Crowder (Walton Goggins, “The Shield”) and Dickie Bennett (Jeremy Davies in his Emmyr-winning role), a mystery man named “Limehouse,” a lethal mob enforcer newly arrived from the Motor City and in a final shocking showdown, his own father – Givens finds himself in everyone's cros­s hairs.
